Stainless Steel 304 316 316L Investment Casting (Silica Sol Precision Casting) Pressure Gauge Connector

Key Features

1. Material Excellence
   • 316L Stainless Steel: Contains 2–3% molybdenum, enhancing corrosion resistance against chlorides (e.g., seawater, brine) and acidic media.
   • Low Carbon Content (≤0.03%): Minimizes carbide precipitation during welding, ensuring weld integrity and reducing intergranular corrosion risk.
2. Thread Specifications
   • Common Thread Types:
     • NPT (National Pipe Taper): 1/4 NPT, 1/2 NPT (standard in North America).
     • BSP (British Standard Pipe): G 1/4 B, G 1/2 B (widely used in Europe and Asia).
     • Metric Thread: M20×1.5 (for international compatibility).
   • Gender Options: Male or female threads to suit diverse piping systems.
3. Pressure & Temperature Ratings
   • Maximum Pressure: Up to 30 MPa (4,350 psi), depending on thread size and wall thickness.
   • Temperature Range:
     • Ambient: -40°C to +140°C (-40°F to +284°F).
     • Media: -40°C to +200°C (-40°F to +392°F) for unfilled gauges; -20°C to +100°C (-4°F to +212°F) for glycerin-filled gauges.
4. Design Robustness
   • Sealing Mechanism: O-ring (FKM) with backup sealing ring (PEEK) for leak-tight performance.
   • Mounting Options: Lower mount (LM) or center back mount (CBM) for flexible installation.
   • Surface Finish: Polished to reduce contamination risk in sanitary applications.

Technical Specifications

Applications

1. Chemical & Petrochemical Plants:
   • Connects pressure gauges to pipelines handling aggressive chemicals (e.g., sulfuric acid, chlorine).
2. Marine & Offshore Technology:
   • Resists saltwater corrosion in shipboard pressure monitoring systems.
3. Pharmaceutical & Food Processing:
   • Sanitary design meets hygienic standards for sterile environments.
4. Oil & Gas Exploration:
   • Withstands high-pressure conditions in drilling and production equipment.

Advantages Over Alternatives

• Corrosion Resistance: Outperforms 304 stainless steel in chloride-rich environments.
• Weldability: Low-carbon content ensures durable welds without post-weld annealing.
• Hygiene Compliance: Electropolished finish prevents bacterial adhesion in food/pharma applications.
• Temperature Stability: Maintains dimensional integrity under extreme thermal conditions.

Quality Assurance

• Certifications: Compliant with ASTM A403, EN 837-1, ASME B40.1, and DIN 16003.
• Testing: Subjected to hydrostatic pressure tests (1.5× working pressure) and helium leak detection for critical applications.
• Traceability: Each connector is marked with material grade, heat number, and manufacturing batch for full traceability.

Conclusion

The 316L stainless steel pressure gauge connector combines unmatched corrosion resistance, high-pressure capability, and precision engineering to deliver reliable performance in the most demanding environments. Its versatility and durability make it the preferred choice for industries where safety, accuracy, and longevity are paramount.
